Biofilms are well recognised in different settings. Endodontic biofilms containing bacteria responsible for bacteraemia and secondary infection of total hip arthroplasties (THA) represent a diagnostic challenge because they are often asymptomatic. Their treatment is difficult and inadequate management of such unrecognised sources of systemic infection can lead to the devastating situation of an infected arthroplasty necessitating implant removal, long term antibiotic treatment and secondary implantation of a new prosthesis. Since about ten percent of secondary infected THA can have a dental origin, this article is intended to give guidelines to all intervening care providers: general practitioner, orthopaedic surgeon and dentist.

Granule neurons of the dentate gyrus (DG) of the hippocampus undergo continuous renewal throughout life. Among cell cycle regulators, cyclin-dependent kinase 2 (Cdk2) is considered as a major regulator of S-phase entry. We used Cdk2-deficient mice to decipher the requirement of Cdk2 for the generation of new neurons in the adult hippocampus. The quantification of cell cycle markers first revealed that the lack of Cdk2 activity does not influence spontaneous or seizure-induced proliferation of neural progenitor cells (NPC) in the adult DG. Using bromodeoxyuridine incorporation assays, we showed that the number of mature newborn granule neurons generated de novo was similar in both wild-type (WT) and Cdk2-deficient adult mice. Moreover, the apparent lack of cell output reduction in Cdk2(-/-) mice DG did not result from a reduction in apoptosis of newborn granule cells as analyzed by TUNEL assays. Our results therefore suggest that Cdk2 is dispensable for NPC proliferation, differentiation and survival of adult-born DG granule neurons in vivo. These data emphasize that functional redundancies between Cdks also occur in the adult brain at the level of neural progenitor cell cycle regulation during hippocampal neurogenesis. [less ▲]

The Zapara Indians in the Upper Amazon are on the verge of disappearing from the linguistic map. This is a fact. And yet, their emergence within the political landscape in Ecuador (but not yet in Peru), has provided them with a greater international visibility as an indigenous group. Most unusually, the accounts of dreams become one of the key elements of new forms of identity practices and identification processes – as those narrated here by two Zapara political leaders will attest. In search of their material and immaterial heritage, these leaders make use of the realm of dreams, using occurred dreams to orient their choices in the reconstruction of a collective memory. The dream, as a tool for engaging in a regredient process or in the return into the past, provides the historical elements that the Indians will then re-inject into their present in order to construct new “traditions”. In this dissertation, I will be describing the mechanisms, the learning of, and the local theories concerning the experience of dreams. In order to be understood, the dream must first circulate, and must have an issuer as a point of departure. Dreaming is also the means for a privileged relationship between human and non- human beings. Throughout this thesis, various systems of memory will be examined based upon empirical data revealing of the dreamt experience, but also of daily life, such as new teaching methods, or the creation of artefacts, produced both by ancestors or contemporaries. These accounts will help us to understand this new process of “Zaparaisation”, which depends as much on a process of ethno-archiving than on ethno-museography, and which awakens the immaterial.

Le secteur Open Source connaît une profonde mutation: à côté de l’idéologie libertaire prônée par ses défenseurs, il migre vers une "économie de marché" au sein de laquelle les acteurs développent désormais de réelles stratégies commerciales. A partir d’une étude exploratoire, basée sur l’analyse de six cas d’entreprises, notre recherche met en évidence les modèles d'affaires privilégiés par ces sociétés pour positionner leur offre de produits/services et générer un retour lucratif à leurs activités. Synthétisés au travers de trois approches distinctes – les logiques de la complexification, du système clos et de l’intermédiation –, ces modèles économiques reflètent des positionnements foncièrement différents par rapport à la philosophie Open Source et soulignent les ressources (au sens de Barney, 1991) que les entreprises mobilisent pour créer un lien de dépendance envers leur clientèle et se forger un avantage concurrentiel durable.

The effect of evaporative drying on the pore size of two series of hybrid silica gels is investigated by combining beam bending on the gels and mercury porosimetry on the aerogels and xerogels with transmission electron microscopy on the xerogels. It is shown that the shrinkage of the pores during drying is different in the two series: in one series the pores shrink proportionally to their volume, in the other the pores collapse until they all reach the same size. The experimental data enable us to discuss the relation between these two different behaviours and the different morphology of the two series of gels. [less ▲]

Aims:The principal aim of this project is to determine the structural parameters of the rapidly pulsating subdwarf B star PG 0911+456 from asteroseismology. Our work forms part of an ongoing programme to constrain the internal characteristics of hot B subdwarfs with the long-term goal of differentiating between the various formation scenarios proposed for these objects. So far, a detailed asteroseismic interpretation has been carried out for 6 such pulsators, with apparent success. First comparisons with evolutionary theory look promising, however it is clear that more targets are needed for meaningful statistics to be derived. Methods: The observational pulsation periods of PG 0911+456 were extracted from rapid time-series photometry using standard Fourier analysis techniques. Supplemented by spectroscopic estimates of the star's mean atmospheric parameters, they were used as a basis for the “forward modelling” approach in asteroseismology. The latter culminates in the identification of one or more “optimal” models that can accurately reproduce the observed period spectrum. This naturally leads to an identification of the oscillations detected in terms of degree ℓ and radial order k, and infers the structural parameters of the target. Results: The high S/N low- and medium resolution spectroscopy obtained led to a refinement of the atmospheric parameters for PG 0911+456, the derived values being T_eff = 31 940 ± 220 K, log g = 5.767 ± 0.029, and log He/H = -2.548 ± 0.058. From the photometry it was possible to extract 7 independent pulsation periods in the 150-200 s range with amplitudes between 0.05 and 0.8% of the star's mean brightness. There was no indication of fine frequency splitting over the 68-day time baseline, suggesting a very slow rotation rate. An asteroseismic search of parameter space identified several models that matched the observed properties of PG 0911+456 well, one of which was isolated as the “optimal” model on the basis of spectroscopic and mode identification considerations. All the observed pulsations are identified with low-order acoustic modes with degree indices ℓ = 0,1,2 and 4, and match the computed periods with a dispersion of only 0.26%, typical of the asteroseismological studies carried out to date for this type of star. The inferred structural parameters of PG 0911+456 are T_eff = 31 940 ± 220 K (from spectroscopy), log {g} = 5.777 ± 0.002, Mast/Msun = 0.39 ± 0.01, log{M_env/Mast} = -4.69 ± 0.07, R/Rsun = 0.133 ± 0.001 and L/Lsun = 16.4 ± 0.8. We also derive the absolute magnitude MV = 4.82 ± 0.04 and a distance d = 930.3 ± 27.4 pc. [less ▲]

Background: Postoperative organ failures commonly occur after major abdominal surgery, increasing the utilization of resources and costs of care. Tissue hypoxia is a key trigger of organ dysfunction. A therapeutic strategy designed to detect and reverse tissue hypoxia, as diagnosed by an increase of oxygen extraction (0,ER) over a predefined threshold, could decrease the incidence of organ failures. The primary aim of this study was to compare the number of patients with postoperative organ failure and length of hospital stay between those randomized to conventional vs a protocolized strategy designed to maintain O2ER < 27%. Methods: A prospective, randomized, controlled trial was performed in nine hospitals in Italy. One hundred thirty-five high-risk patients scheduled for major abdominal surgery were randomized in two groups. All patients were managed to achieve standard goals: mean arterial pressure > 80 mm Hg and urinary output > 0.5 mL/kg/h. The patients of the "protocol group" (group A) were also managed to keep O2ER < 27%. Measurements and main results: In group A, fewer patients had at least one organ failure (n = 8, 11.8%) than in group B (n = 20, 29.8%) [p < 0.05], and the total number of organ failures was lower in group A than in group B (27 failures vs 9 failures, p < 0.001). Length of hospital stay was significantly lower in the protocol group than in the control group (11.3 +/- 3.8 days vs 13.4 +/- 6.1 days, p < 0.05). Hospital mortality was similar in both groups. Conclusions: Early treatment directed to maintain O2ER at < 27% reduces organ failures and hospital stay of high-risk surgical patients. Clinical trials.gov reference No. NCT00254150. [less ▲]

Purpose of review Patients in a vegetative or minimally conscious state continue to pose problems in terms of diagnosis, prognosis and treatment. Despite recent waves of international media attention following Terri Schiavo's death and the 'miracle recovery' of Terry Wallis, research efforts aimed at increasing our knowledge about brain function in these conditions remain scarce and must address a series of difficulties, including financial and ethical barriers. Here we review current possibilities and limitations of clinical and para-clinical assessment of chronic disorders of consciousness. Recent findings During the past year the field has witnessed publication of significant, yet isolated, case reports in top-ranking journals, including Science and Nature. Such milestone reports and other impressive recent technological advances in the study of vegetative and minimally conscious patients reveal enthralling areas of science that must find their way to clinical medical reality. Summary Consciousness is a subjective experience whose study has remained within the purview of philosophy for millennia. That has finally changed, and empirical evidence from functional neuroimaging offers a genuine glimpse at a solution to the infamous mind-body conundrum. New technological and scientific advances offer the neurological community unique ways to improve our understanding and management of vegetative and minimally conscious patients. [less ▲]
